“Immunization has been a great public health success story. The lives of millions of children have been saved, millions have the chance of a longer healthier life, a greater chance to learn, to play, to read and write, to move around freely without suffering.”
Disease prevention is the most cost-effective health-care intervention available. Because immunization helps to inhibit the spread of disease, many people can be protected from illness and death.
With the exception of clean, safe drinking water, no human endeavor rivals immunization in combating infectious diseases and reducing mortality rates.
